Assessment of ochratoxin A occurrence in Argentine red wines using a novel sensitive quechers-solid phase extraction approach prior to ultra high performance liquid chromatography-tandem mass spectrometry methodology
(John Wiley & Sons Ltd, 2017-06)
BACKGROUND: The assessment of ochratoxin A (OTA) in wine is relevant for food safety and its continuous control allows to reduce the risk of intake. Thus, a novel sensitive QuEChERS-SPE (Quick, Easy, Cheap, Effective, ...
A simple, rapid and novel method based on salting-out assisted liquid–liquid extraction for ochratoxin A determination in beer samples prior to ultra-high-performance liquid chromatography coupled to tandem mass spectrometry
(Taylor & Francis, 2018-08)
A novel, simple, easy and cheap sample treatment strategy based on salting-out assisted liquid-liquid extraction for ochratoxin A (OTA) ultra-trace analysis in beer samples using ultra-high-performance liquid chromatography-tandem ...
A novel solid phase extraction Ultra high performance liquid chromatography tandem mass spectrometry method for the quantification of ochratoxin A in red wines
(Elsevier, 2015-04)
A novel and advanced technology on solid phase extraction column prior to liquid chromatography coupled to tandem mass spectrometry has been used for the determination of ochratoxin A in red wine samples. Due to the need ...
Determination of ochratoxin A in coffee and tea samples by coupling second-order multivariate calibration and fluorescence spectroscopy
(Elsevier Science, 2020-11-01)
A new method to quantify the mycotoxin ochratoxin A (OTA) in coffee and tea samples is proposed based on second-order multivariate calibration and excitation-emission fluorescence matrix (EEFM) data. Experimental conditions ...
Growth and ochratoxin A production by Aspergillus niger group strains in coffee beans in relation to environmental factors
(Wageningen Academic Publishers, 2010-02)
The effect of water activity (aW), temperature and their interactions on lag phase, mycelial growth rate and ochratoxin A (OTA) production at 7, 14 and 21 days of incubation of two OTA-producer strains belonging to Aspergillus ...
Inhibition of growth and ochratoxin A biosynthesis in Aspergillus carbonarius by flavonoid and nonflavonoid compounds
(Springer Heidelberg, 2009-09-18)
The effect of naturally occurring phenolic compounds on Aspergillus carbonarius growth and ochratoxin A (OTA) production was studied. Caffeic acid and the flavonoids, rutin and quercetin, were added to Czapek Yeast ...
Lactobacillus reuteri CRL 1098 and Lactobacillus acidophilus CRL 1014 differently reduce in vitro immunotoxic effect induced by Ochratoxin A
(Pergamon-Elsevier Science Ltd, 2012-12-05)
Ochratoxin A (OTA) is a widespread mycotoxin contaminating several food products which causes detrimental health effects. The ability of Lactobacillus reuteri CRL 1098 and Lactobacillus acidophilus CRL 1014 to prevent OTA ...
Influence of planococcus ficus on aspergillus section nigri and ochratoxin a incidence in vineyards from argentina
(Wiley Blackwell Publishing, Inc, 2010-07-09)
Aim: The aim of this work was to evaluate the effect of Planococcus ficus infection in red wine grapes on Aspergillus section Nigri and ochratoxin A (OTA) contamination. Methods and Results: During 2006/2007 and 2008/2009 ...
